Bundle cache [Collection]

The bundle cache is a cell-wide store (or server-wide for single-server systems) of bundles that are referenced by OSGi applications, and that have been downloaded from both internal and external repositories. We can get an up-to-date list of the bundles in the bundle cache, check if all bundles have been successfully downloaded, and request that one or more bundles be downloaded again.

A bundle download is requested when you import an enterprise bundle archive (EBA) file as an asset, and when you update an asset to use new bundle versions. A bundle download is also requested when you add a composite bundle as an extension to a composition unit.

To view this panel in the administrative console, click the following path:

Environment > OSGi bundle repositories > Bundle cache.

To act on one or more of the listed items, select the check boxes next to the names of the items on which to act, then use the buttons provided.

Bundle Symbolic Name and Version

The non-localizable name and version identifier for this bundle. The bundle symbolic name, together with the bundle version, uniquely identifies a specific version of a bundle.

State

The current state of the bundle. This is one of the following states:

Unknown

The bundle is not in the bundle cache and there has been no request to download the bundle.

Download requested

A request has been issued to download the bundle, but the download has not yet begun.

Download

The bundle is downloading.

Downloaded

The bundle download is complete.

Failed

The bundle download has failed.

Trace information is available in the "Bundle download exceptions" pane of the Bundle cache [Settings] panel.

To restart the download, select the bundle then click Download Bundle Again on this panel.

Unsaved

The bundle is unsaved if we have imported an asset and not yet saved your changes to the master configuration.

The bundle is not downloaded until you save your changes.

Download Status

The download status tells you how much of the bundle has been downloaded. If the download is complete, "100%" is displayed. If a download is in progress and the total expected file size is known, the approximate percentage complete is displayed. If a download is in progress and the total expected file size is not known, for example because the file is being downloaded through an FTP site, the number of bytes downloaded so far is displayed.

Size

The size is the total size of the bundle, displayed in the most appropriate units (usually kilobytes or megabytes). If the bundle size is not known, because the bundle download has not yet completed, "Unknown" is displayed.

Buttons

Download Bundle Again	If one or more bundles have not downloaded successfully, select the unsuccessful bundles then click this button to request that they are downloaded again.
Refresh List	Get an up-to-date list of the bundles in the bundle cache.
